ABSTRACT Heat transport in magnetohydrodynamic (MHD) flow has given huge contribution in the field of engineering and biological systems like material selection, machinery efficiency, reaction kinetics, bio preservation, cryosurgery, heat, or cold treatments to destroy tumors, and treatment of several diseases by controlling the physical parameters. This research inquires the heat transport inMHDCross nanofluid via thermal conductivity with presence of Brownian motion, thermophoresis, and binary chemical reaction in cylindrical coordinates. Velocity of nanofluid is observed through imposed perpendicular magnetic dipole field and behavior concentration is depicted by activation energy (AE). Judgment of physical quantities is made through statistical graphs for nearly all involved parameters. Cross fluid model fetches the partial differential equations (PDEs) from Navier Stokes equation and the well-known shooting technique converted PDEs into ordinary differential equations. Further, for numerical solutions of obtained ODEs are passed through Matlab scheme bvp4c.
